Karissa felt only an emptiness, an aching void, a heart crushing loss whenever her throat wasn’t being used to give a man pleasure.

She had spent so many years fighting an ever present ennui, until the first time a man thrust the length of his cock down her throat. The exhilaration of that moment, the way the air was cut off from her lungs, the salty cum erupting against the back of her throat - it was then that she understood her calling in life.

She was created for pleasure, her mouth a vessel meant to hold the pistoning cocks of men as they used her throat for their pleasure.  She understood why she had been born and could at last chase after her happiness, by striving to swallow as many cocks as possible.
